You can judge an evaporator coil by its features

The AlumaFin7 evaporator coil offers HVAC contractors an efficient option for installations in space-constrained homes. Its all-aluminum, 21-inch depth design also provides additional features and benefits to help create great value for enhanced indoor comfort.

• The 7mm grooved aluminum tubing enhances the heat transfer properties of the refrigerant.
• The multi-louvered fins are acid-etched to help drain condensate faster, compared to aluminum fins that are not acid-etched. These combined features help deliver improved airflow with minimal static pressure.
• A corrosion resistant thermoplastic drain pan features a ‘no water-retention’ design.
• The triangle plate’s thickness adds structural integrity.
• The single-piece access panel with a tight seal helps to keep conditioned air from escaping.

The 7mm grooved aluminum tubing help provide enhanced turbulence of refrigerant.
